It's strange they are close.
I hope you are not missing the public entrance because it is not from the main embassy gates. Best way is to call them and if they dont attend it due to any reason, record a message, they do reply voice messages. And one more thing they collect documents from 9-12 in the morning and then they have a break and i think reopens at 2 or 3.
I did called but they are closed from both getes
